Air quality and meteology data (download by https://goo.gl/UXEw9C):
1. Air quality data are stored in DB:Air, Collection:Stations
2. Meteorology data are stored in DB:forecastio, Collection:Beijing
3. Information of the stations: station_location.csv
Air data and meteorology data are separatedly exported to files with "mongodump -d db_name -o dir" command. You can use "mongorestore -d db_name -o dir/*" commend to separatedly import them into Mongo DB.
1. The Stock Price Data: extracted from the Google Finance API(http://files.statworx.com/sp500.zip).
It contains minutely price records of 500 stocks from S&P 500, ranging from 3rd April to 31th August in 2017.
2. Background Knowledge of Stocks: It contains correlative companies information of S&P 500 component stocks, which is stored in a knowledge graph, extracted from Wikipedia
3. Real-time Text Data for Stocks: It contains social media data related to S&P 500 index and stocks when the stock market opening. We have extracted 98617 tweets with respect to S&P 500 index, from 3rd, April, 2017 to 31st, August, 2017.
